Title: Calculating sound dispersion in flowing media -  separating surface into partial areas small compared with wavelengths produced by sound pressure of vibrating surface
Inventor: ECCARDT PETER CHRISTIAN DIPL I
IPC: G01F1/66
Filed: 1990-09-28
Abstract: The calculation is based on the Huygenic principle according to which the vibrating surface producing sound pressure is divided into small surface areas that are small compared with the generated wavelengths. The spherical waves generted by these partial surface areas can be calculated at a reception point by their in-phase modulation. The scattering of each of these spherical waves through the flowing medium is calculated. The superimposing of the spherical waves produced is carried out at the receiving station. A finite number of selectable formed reflectors in the sound dispersion path is assurred. Their surfaces are taken again as starting points of spherical waves. USE/ADVANTAGE - Rapid calculation for optimising ultrasonic flowmeter.

Patent DE-4118874-A1 (DE)
Inventor: MIETH HANS OTTO DIPL ING
IPC: F16K25/02
Filed: 1991-06-07
Abstract: Disclosed are a process for cleaning a double seat valve, in particular a low-leakage or non-leaking double seat valve; and a valve device for carrying out the process. The aim is to ensure among other things that the relevant areas of the double seat valve can be cleaned with the minimum of detergent and/or disinfectant, in the interests of economy and the environment. To this end, provision is made in the process to clear a passageway, which leads off from part of the valve casing, by partially opening a closure element; the detergent stream flows through this passageway and cleans both the passageway (A or C) of the rod at its branching off point and at least one of the following areas: the other rod passageway (C or A), the leakage cavity, or the now accessible seat area. To facilitate the process, it is proposed inter alia that a drilling (4d) should be provided in the second control rod (4b) along the length thereof; this drilling should be connected with the passageway of the first control rod (3a) in section (1a) of the valve casing, and with the passageway (C) of the pipe (4a) in section (1b) of the valve casing. It is also proposed that the connecting path between the drilling (4d) and the passageway (A) should have a branching off point (V), from which is provided a further connection with an annular gap situated between the first control rod (3a) and the second control rod which is arranged coaxially in the first. The annular gap (9) is connected to the leakage cavity (6), and partial opening of the first closure element (3) counter to the opening movement of the valve clears the passageway (A) (or passageway (C) if the second closure element is activated), allowing the detergent stream to flow and divide at the dividing point into subsidiary streams (R1 and R2).

Title: Central locking for vehicle - has seat occupancy sensors to inhibit locking from outside if any seat is occupied
Inventor: KUHN STEFAN
IPC: E05B65/36
Filed: 1991-07-04
Abstract: The vehicle has pressure sensor switches on each seat. These switches (25,26,27,28) are connected to the central locking circuit in such a way that the circuit cannot lock the door locks from the outside if any seat is occupied. The central locking drive (17) operates the locks by hydraulic servo pressure, or by individual electric servo motors. The pressure levels in the switches is set to ignore small luggage items, but is sensitive enough to detect small children. This prevents children being locked into the vehicle. The front doors have operated locks while the rear doors are operated by the catches alone. ADVANTAGE - Failsafe central locking system, simple addition to existing systems.

IPC: H01L29/747
Filed: 1991-07-10
Abstract: Crystals are formed by exposing a semiconductor material melt (16) to an impurity soluble in the semiconductor material and partially pptd. in the material after solidification, and forming a single crystal (20) with embedded impurity from part of the melt (16), the initially formed part of the single crystal having a lower impurity concn. than final part of the single crystal. Formation involves forming rod (20), cutting the rod into wafers, and simultaneously forming parts in the wafers and pptg. part of the impurity of the wafers. Pref. the semiconductor material is Ge or esp. Si and the impurity is N, C or esp. O. The wafers, obtd. from the single crystal, are pref. heated uniformly to a temp. which promotes nucleation of the impurity for the same time. ADVANTAGE - The impurity concn. along the crystal is inversely related to the duration of exposure of each portion of the growing crystal to temps. which promote nucleation of pptes.  to ppte. uniform crystal concn. along length.
Patent DE-4126631-A1 (DE)
Inventor: BRUECKNER HERMANN ING GRAD
IPC: F22B1/18
Filed: 1991-08-12
Abstract: Waste-heat steam generators of this kind include an evaporator or several evaporators arranged in different pressure stages, at least one continuous-throughput evaporator being fitted, preferably in a high-pressure stage (HD VD, HDÜ). The water flow in the continuous-throughput evaporator (HD VD) passes in the same direction as the hot gas stream (2). The invention calls for the continuous-throughput evaporator to be made up of two elements (HD VD 1 and HD VD 2), the flow in both being in the same direction as the gas flow. The amounts of heat transferred to each these two elements (HD VD 1 and HD VD 2) are in the ratio between 7:3 and 10:1 and the first element (HD VD 1) through which the water passes lies down-stream, with respect to the gas flow (2), from the second element (HD VD 2). Waste-heat steam generators designed in this way have a very uniform flow distribution in the parallel tubes in the continuous-throughput evaporator and are suitable, above all, for use in the exhaust-gas flow (2) from gas turbines or in the coolant flow from high-temperature nuclear reactors.
